Four-wave mixing — is an intermodulation phenomenon in optical systems, whereby interactions between 3 wavelengths produce a 4th wavelength in the signal. It is similar to the third order intercept point in electrical systems. Four wave mixing can be compared to… … Wikipedia
Cross-polarized wave generation — Fig. 1. Cross polarized wave (XPW) generation is a nonlinear optical process that can be classified in the group of frequency degenerate [four wave mixing] processes. It can take place only in media with anisotropy of third order nonlinearity. As … Wikipedia

Nonlinear optics — (NLO) is the branch of optics that describes the behaviour of light in nonlinear media, that is, media in which the dielectric polarization P responds nonlinearly to the electric field E of the light. This nonlinearity is typically only observed… … Wikipedia
Squeezed coherent state — In physics, a squeezed coherent state is any state of the quantum mechanical Hilbert space such that the uncertainty principle is saturated. That is, the product of the corresponding two operators takes on its minimum value::Delta x Delta p =… … Wikipedia
Coherent anti-Stokes Raman spectroscopy — Coherent anti Stokes Raman spectroscopy, also called Coherent anti Stokes Raman scattering spectroscopy (CARS), is a form of spectroscopy used primarily in chemistry, physics and related fields. It is sensitive to the same vibrational signatures… … Wikipedia
Vier-Wellen-Mischung — (engl. Abk. FWM = Four Wave Mixing) ist eine intermodulare Verzerrung in optischen Systemen. Als Untersuchungsmethode findet sie Anwendung in der optischen Spektroskopie, z. B. bei der Erzeugung Laserinduzierter Gitter. Wenn drei… … Deutsch Wikipedia
Dispersion (optics) — This article is about dispersion of waves in optics. For other forms of dispersion, see Dispersion (disambiguation). In a prism, material dispersion (a wavelength dependent refractive index) causes different colors to refract at different angles … Wikipedia
Nonlinear Schrödinger equation — This page is about the equation iψt = −½ψxx + κ|ψ|2ψ. For the equation iψt = −½ψxx + V(x)ψ + κ|ψ|2ψ, used in Bose–Einstein condensate theory, see Gross–Pitaevskii equation. In theoretical physics, the nonlinear Schrödinger equation (NLS) is a… … Wikipedia
Acousto-optic modulator — An acousto optic modulator (AOM), also called a Bragg cell, uses the acousto optic effect to diffract and shift the frequency of light using sound waves (usually at radio frequency). They are used in lasers for Q switching, telecommunications for … Wikipedia
Slow light — is the literal slowing of the speed of light. It is the propagation of an optical pulse or other modulation of an optical carrier at a very low group velocity. The term is usually only applied when the velocity is at least hundreds of times… … Wikipedia
